回顾中国城乡家庭调查的历史，描述调查内容与近年变化，指出数据在可用性、收集和使用方面的问题，帮助研究者了解该数据源的限制。
As China has become a more important player in international markets in recent decades, an increasing number of researchers have become interested in China's agriculture. China's rural and urban household surveys, begun in 1955, have traditionally been an important source of data, but problems of accuracy and availability have seriously limited their use. This paper provides a historical overview of the surveys, describes the surveys' contents and major changes in recent years, and identifies problems in data availability, collection, and use.
